发明名称 FAHRZEUGGETRIEBE MIT EINER PARKSPERRE UND VERFAHREN ZUR STEUERUNG DESSELBEN
摘要 A vehicle transmission having shifting elements (A-E) and a parking brake for locking a drive train output and a method for controlling the transmission. Activation of the parking brake depends on a driver's control action. Deactivating the parking brake, when the vehicle is on a slope greater or lesser than a preset value and depending on the slope, a combination of shifting elements (A, D) or (B, D) frictionally slip, such that the output rotates against the strain on a parking brake locking element, caused by the slope, to partially eliminate this strain. Next, one of shifting elements (C, A or B) engages locking the output. The parking brake is then released and finally, the engaged shifting element (C or A or B) is disengaged in a regulated manner, such that the output can be driven according to the driver's control action.
